Rationale for changing the name of our Verconia sp. 1 to Ceratosoma sp. 1 is as follows:

- We found our first specimen of this species in 2012. - It had a very similar appearance to a couple of Verconia species (Noumea at the time)
but did not match properly so was listed as an sp.
- It was subsequently noticed that in NSSI of 2008 a specimen of very similar appearance was called Ceratosoma sp. 2 but we were not at all
convinced on just external features.
- It has also been listed in NSSI 2015 as Ceratosoma (sp. 1 this time)
- It was thought they must have had a good reason for this and on re-reading: Traditional Taxonomic Groupings Mask Evolutionary History:
A Molecular Phylogeny and New Classification of the Chromodorid Nudibranchs
- Johnson & Gosliner, 2012 (Table S2 page 6) it was noticed that Ceratosoma sp. 2 of NSSI 2008 had actually been sequenced
and fitted within the taxonomy of Ceratosoma.
- With regard to variation in colour, specifically the amount of red pigment, Terry Gosliner has commented on Facebook (Nudibranch Central) that this is the case.
